Grams of Sugar to Tsp Formula

The formulas below convert sugar mass to teaspoons and back using bulk density for the chosen sugar type and the selected teaspoon volume.

tsp = (grams) / (d × Vₜₛₚ)
  • US teaspoon = 4.92892 mL
  • Metric teaspoon = 5 mL.
  • Granulated sugar density d ≈ 0.85 g/mL (≈ 4.19 g per US tsp)
  • Powdered sugar density d ≈ 0.50 g/mL (≈ 2.46 g per US tsp)
  • Brown sugar, light (packed) d ≈ 0.93 g/mL (≈ 4.58 g per US tsp)
  • Brown sugar, dark (packed) d ≈ 1.02 g/mL (≈ 5.03 g per US tsp)

* Granulated sugar, US tsp: density d ≈ 0.85 g/mL → 1 tsp ≈ 4.19 g.

How do you convert grams of sugar to teaspoons? Use tsp = grams ÷ (density × tsp mL); for granulated sugar with US teaspoons, multiply grams by ≈0.23873 (since 1 US tsp ≈ 4.19 g).

How do you convert teaspoons of sugar to grams? Multiply teaspoons by density × tsp mL; for granulated sugar (US), grams ≈ tsp × 4.1896.

Example Problem

Convert 18 g of granulated sugar to US teaspoons.

Use tsp = grams ÷ (d × Vtsp) with d = 0.85 g/mL and Vtsp = 4.92892 mL.

tsp = 18 ÷ (0.85 × 4.92892) = 18 ÷ 4.189582 ≈ 4.297 tsp
